 * a {@link module:ui/labeledfield/labeledfieldview~LabeledFieldView labeled view} in the DOM.
 *
 * The helper does the following:
 *
 * * It sets the color input `id` and `ariaDescribedById` attributes.
 * * It binds the color input `isReadOnly` to the labeled view.
 * * It binds the color input `hasError` to the labeled view.
 * * It enables a logic that cleans up the error when the user starts typing in the color input.
 *
 * Usage:
 *
 * ```ts
 * const colorInputCreator = getLabeledColorInputCreator( {
 *   colorConfig: [ ... ],
 *   columns: 3,
 * } );
 *
 * const labeledInputView = new LabeledFieldView( locale, colorInputCreator );
 * console.log( labeledInputView.view ); // A color input instance.
 * ```
 *
 * @internal
 * @param options Color input options.
 * @param options.colorConfig The configuration of the color palette displayed in the input's dropdown.
 * @param options.columns The configuration of the number of columns the color palette consists of in the input's dropdown.
 * @param options.defaultColorValue If specified, the color input view will replace the "Remove color" button with
 * the "Restore default" button. Instead of clearing the input field, the default color value will be set.
 * @param options.colorPickerConfig The configuration of the color picker. You could disable it or define your output format.
